I'm having problems with the Minilab 3501f.

When I turn on the minilab, the dryer, racks, and circulation pumps don't activate; what do you think the problem is?

Maybe it is just in program timer mode. Press and hold the green button on the sorter and see if the machine comes on.

Quizá simplemente esté en modo temporizador de programa. Pulsa y mantén pulsado el botón verde del clasificador y comprueba si la máquina se enciende.

I've been pressing the green button, but nothing is activating.

On board J-391329-01, those LEDs are lit, yet the process, the dryer, and the pumps aren't activating. Where is the fault, or where is power missing that is needed to activate them?

Check the resistance of the solution level float sensors between Pins 3 & 4 and Pins 5 & 6 for the CD, BF and STB float switches. They should all be close to 0 ohms.

The plug numbers are J/P784, 785, & 789 look for the black, blue and red wires from the float switches.
